FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 289,061, dated November27, 1883. Application filed October 22, 1883. (No model.)

To ail whmn it 7771661,! concern:

Be it known that we, GEORGE Bonsr and FREDERICK WILL, both of the cityof Rochester, in the county of Monroe and State of New York,haveinvented a certain new and useful Improvement in Fire-Escapes; and we dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, in which Figure l is a perspective view of a window with ourimprovement applied thereto. Fig. 2- is a side elevation of theattachment in its extended form. Fig. 3 is a similar view in the foldedform.

Our improvement relates to that class of fire-escapes in which a jointedframe is at tached to the window-casing, capable of being projectedoutward for the attachment of a rope, wire, ladder, or other device, bywhich a person may descend without coming in contact with window sillsor cornices; or of being folded up in compact form at the sides of thewindow, and without obstructing the window, as hereinafter more fullydescribed.

The invention consists in the combination of a wire forming a squareloop pivoted to the sides of the window-frame and two side wires formingangular braces, also pivoted to the sides of the window-frame at thebottom, and provided with eyes at their top,'which slide upon the sidesof the upper wire, the arrange ment being such that the frame can befolded upward and rest out of the way in the rabbets of thewindow-frame, or can be extended to support the rope, the eyes in thatcase striking the front of the upper wire and sustaining the parts. 4

In the drawings, A shows the upper wire, which is simply bent intosquare or rectangular form, consisting of the outer cross-length, a, andtwo side lengths, b b, the latter having eyes 0 c at their inner ends,which are pivoted to the sides of the window-frame.

B B are the two side wires that form the braces. At the lower end theyhave eyes d d, which are also pivoted to the sides of the window-frame,and at the top they have other eyes, f. which are bent at right anglesand fit loosely upon the sides b b of the upper wire, A.

The device, when extended, is of crane form, and substantially a righta-ngled triangle, as shown in Fig. 2, the upper wire being pivotedmidway of the length of the window and the lower wires pivoted at thebottom of the window. When the frame is extended, as shown in Figs. 1and 2, a rope, wire, flexible ladder, or similar device, 0, may beattached to the outer length, a, thereby enabling a person to descendfree of window-sills, cornices, &c., and the rope can be slippedlaterally to any desired position the full length of said length a.

e are aware that various folding devices are already in use on windowsfor the attachment of a rope and for throwing the rope out beyondcornices. Therefore we limit our claim to the particular combination ofparts herein shown and described. This attachment being all connectedtogether, is opened or closed by simply turning one arm up or down.There is no adjustment of separate parts to be made. When the device isfolded up, as in Fig. 3, the sides lie compactly in the rabbet of thewindow-frame, the cross-length being raised so high that it does notobstruct vision, and is not in the way. When lowered, the eyes of thebraces slide on the sides of the main wire, and when the device is fullylowered said eyes strike the cross-piece a, thereby forming a stop,which limits the movement of the frame, holds it in an extendedposition, and gives great strength and stiffness.

An awning maybe readily attached to the frame by attaching the upperedge of the awning to fixed hooks or clamps at the top of the window andthe lower edge to the length a; The awning will then fold with theframe. A button or other device may be used for holding the frame in thefolded position.

Instead of wire, as described, iron rodround, square, or of other formin cross-section-may be used.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is

In a fire-escape,

the combination of a wire,

A, forming a square loop pivoted to the sides of the window-frame, andtwo side Wires, B B, pivoted at one end to the Window-frame, and formingangular braces, the opposite end having eyes ff, which rest and slidefreely on the sides of the Wire A, said eyes connecting the parts sothat they move all together, and forming stops to limit the movement ofthe frame in extending, as herein shown and described.

In witness whereof we have hereunto signed 10 our names in the presenceof two subscribing witnesses.
